MTA Chair Pat Foye and Interim New York City Transit President Sarah Feinberg, have announced that the subway will close overnight in order to improve subway cleaning. For the duration of the Covid-19 crisis, the subway will close between 1 and 5 every night for disinfection. Ben Kabak has covered this to some extent; I’m going to focus on best industry practices, which do not require a shutdown. There are some good practices in Taipei, which has regular nighttime shutdowns but sterilizes trains during the daytime as well. It appears that the real rub is not cleaning but homelessness – the city and the state are both trying to get homeless people off the subway and onto the street.
How to disinfect a subway system
Alex Garcia of Taipei Urbanism shared with me what the Taipei MRT plans on doing in response to the virus, depending on how much it affects the system. As soon as there are any domestic cases within Taiwan, the plan says,
a. Sterilize equipment in each station that passengers might frequently come into contact with. (Sterilize once every 8 hours)
b. Carriages: Cleaning and sterilization before the daily operational departure and again when the carriage returns back to the terminal each day.
c. Place hand sanitizer devices at the information counter of the station for public use.
Moreover, if an emergency is declared, then the frequency of cleaning is to increase:
a. Station :
1. Sterilize equipment that passengers might frequently come into contact with at each station. (Sterilize once every 4 hours)
2. Daily disinfection of public station facilities: After operational hours the whole station, including passenger traffic flow areas and facilities, will be disinfected.
b. Carriage :
1. Sterilize equipment that passengers might frequently come in contact with. Sterilize once every 8 hours when the carriage returns to the terminal station.
2. Daily wipe down of entire carriages with disinfectant before each day’s first departure.
3. Once notified by the health authority about any confirmed or suspected case that have traveled on the MRT, intensify the cleaning and disinfection along the route taken by the passenger within 2 hours.
Moreover, the Taipei plan calls for providing all frontline workers with protective equipment, including masks, goggles, and hand sanitizer, as soon as any domestic case of the virus is detected. Moreover, all staff are subject to temperature checks at the start of the day, to prevent sick workers from infecting healthy ones. This way, infection levels among workers can be kept to a minimum, allowing service to proceed without interruption.
It is noteworthy that the frequent cleaning regimen operates during the daytime, and not just overnight. Sterilizing trains every 8 hours means working around their service schedules, disinfecting them during off-peak periods with lower frequency. Taipei has not cut weekday service frequency, only weekend frequency, and the weekday peak-to-base ratio is low, about 1.5 on the Green Line.
With these measures in place, and similar vigilance across Taiwanese society, the country has gone 6 days without any new case of the virus. There is no lockdown and never was one, and Taipei MRT ridership only fell 15-16% on weekdays.
What New York is doing
Foye and Feinberg announced that the subway would close overnight between 1 and 5 am so that trains could be disinfected once per day. Is daily disinfection sufficient? Almost certainly not, given the spread of the virus around the city. Does it take four hours? Of course not, cleaning can be done in minutes. And must it be done at night? Again no, New York has cut so much service that there’s a large fleet of spare trains, making rotating equipment between service and cleaning easy. It’s likely that it is possible to sterilize trains every roundtrip while they wait at the terminal.
The goal here is not about cleanliness. The subway is dirty and getting worse as cleaning staff get sick and can’t come to work, but a program designed to improve the system would look profoundly different. It would equip subway workers with protective gear, especially the cleaners; it would keep running service; it would look for ways to eliminate fomites like the push turnstiles; it would disinfect trains and stations at short intervals.
The homelessness issue
There are serious concerns with homelessness in New York, as in many other cities. This is aided by sensationalist reporting that blames homeless people for any number of problems, playing to middle-class prejudices about visible poverty. As Ben notes, NYPD swept the subway with cops but not social workers. Hotels are empty all over the city, but there is no attempt at using them for either centralized quarantine or extra shelter space. There are existing shelters, but they are unsafe and people who have been unsheltered for a while know this and avoid them for a reason.
New York is a big, expensive, high-inequality city. It has visible poverty, including homelessness. It could offer homeless people housing – empty hotels would do, employing hotel workers to do work that is already done at shelters by overtaxed volunteers. The problem is that many aggrieved people want medieval displays of police power against people who it is okay to be violent toward; they do not want to solve problems. This issue is not unique to New York: in San Francisco, sanisette installations ran into the problem that one stall had people defecating on the floor, leading the city to decide to staff every sanisette 24/7, turning what was designed as a self-cleaning system for high-cost cities for €14,400 a year per unit into a $700,000/year money sink. American cities spend millions in enforcement to avoid spending pennies on social work.
Who is being empowered?
The broader question is whether the subway is dirty because of homeless people or because of inadequate cleaning, poor training for cleaners, lack of protective equipment, etc. The vast majority of dirt one sees on trains has pretty obvious origins in ordinary if antisocial riders: spilled drinks, gum stuck to the floor, overflowing trash cans, wrappers thrown on the tracks. However, it is convenient to blame homeless people for this – they can’t politically fight back, and many law-and-order voters and political operatives relish the sight of a cop dragging someone off the train.
This leads to the question, who is being empowered by blame? Any explanation of why things don’t work empowers someone, and explanations are easier to accept if they empower local political forces that the mainstream pays attention to. For example, if I say costs are high because of union pensions, then this automatically empowers the Manhattan Institute and other anti-union forces in the city; and if I say costs are high because managers micromanage and humiliate workers too much, then this empowers the unions.
The upshot is that blaming flagging subway ridership on homeless people making riders uncomfortable empowers law-and-order voters and middle-class people who dislike seeing visible poverty, both of which are groups that even relatively liberal political operatives pay attention to. In contrast, blaming flagging ridership on technical issues with speed and frequency empowers technocrats, who are usually politically invisible, and when they’re not, this can lead to a clash of authority, as seen in Governor Andrew Cuomo’s sidelining of Byford, leading to the latter’s resignation.
This cascades to cleaning. Taipei shows how one can clean trains and stations during service. New York should learn, but that means listening to people who are familiar with Taiwanese practices, and maybe synthesize with other clean Asian systems. Shutdowns that force essential workers onto slow buses and taxis are a terrible policy, but they’re a policy the current leadership does not need to talk to people in a foreign country to implement.
I want to follow up on what I wrote about speed zones a week ago. The starting point is that I have a version 0 map on Google Earth, which is far from the best CAD system out there, one that realizes the following timetable:
This is inclusive of schedule contingency, set at 7% on segments with heavy track sharing with regional rail, like New York-New Haven, and 4% on segment with little to no track haring, like New Haven-Providence. The purpose of this post is to go over some delicate future-proofing that this may entail, especially given that the cost of doing so is much lower than the agency officials and thinktank planners who make glossy proposals think it should.
What does this entail?
The infrastructure required for this line to be operational is obtrusive, but for the most part not particularly complex. I talked years ago about the I-95 route between New Haven and southern Rhode Island, the longest stretch of new track, 120 km long. It has some challenging river crossings, especially that of the Quinnipiac in New Haven, but a freeway bridge along the same alignment opened in 2015 at a cost of $500 million, and that’s a 10-lane bridge 55 meters wide, not a 2-track rail bridge 10 meters wide. Without any tunnels on the route, New Haven-Kingston should cost no more than about $3-3.5 billion in 2020 terms.
Elsewhere, there are small curve easements, even on generally straight portions like in New Jersey and South County, Rhode Island, both of which have curves that if you zoom in close enough and play with the Google Earth circle tool you’ll see are much tighter than 4 km in radius. For the most part this just means building the required structure, and then connecting the tracks to the new rather than old curve in a night’s heavy work; more complex movements of track have been done in Japan on commuter railroads, in a more constrained environment.
There’s a fair amount of taking required. The most difficult segment is New Rochelle-New Haven, with the most takings in Darien and the only tunneling in Bridgeport; the only other new tunnel required is in Baltimore, where it should follow the old Great Circle Tunnel proposal’s scope, not the four-track double-stack mechanically ventilated bundle the project turned into. The Baltimore tunnel was estimated at $750 million in 2008, maybe $1 billion today, and that’s high for a tunnel without stations – it’s almost as high per kilometer as Second Avenue Subway without stations. Bridgeport requires about 4 km of tunnel with a short water crossing, so figure $1-1.5 billion today even taking the underwater penalty and the insane unit costs of the New York region as a given.
A few other smaller deviations from the mainline are worth doing at-grade or elevated: a cutoff in Maryland near the Delaware border in the middle of what could be prime 360 km/h territory, a cutoff in Port Chester and Greenwich bypassing the worst curve on the Northeast Corridor outside major cities, the aforementioned takings-heavy segment through Darien continuing along I-95 in Norwalk and Westport, a short bypass of curves around Fairfield Station. These should cost a few hundred million dollars each, though the Darien-Westport bypass, about 15 km long, could go over $1 billion.
Finally, the variable-tension catenary south of New York needs to be replaced with constant-tension catenary. A small portion of the line, between New Brunswick and Trenton, is being so replaced at elevated cost. I don’t know why the cost is so high – constant-tension catenary is standard around the world and costs $1.5-2.5 million per km in countries other than the US, Canada, and the UK. The Northeast Corridor is four-track and my other examples are two-track, but then my other examples also include transformers and not just wires; in New Zealand, the cost of wires alone was around $800,000 per km. Even taking inflation and four tracks into account, this should be maybe $700 million between New York and Washington, working overnight to avoid disturbing daytime traffic.
The overall cost should be around $15 billion, with rolling stock and overheads. Higher costs reflect unnecessary scope, such as extra regional rail capacity in New York, four-tracking the entire Providence Line instead of building strategic overtakes and scheduling trains intelligently, the aforementioned four-track version of the Baltimore tunnel, etc.
The implications of cheap high-speed rail
I wrote about high-speed rail ridership in the context of Metcalfe’s law, making the point that once one line exists, extensions are very high-value as a short construction segment generates longer and more profitable trips. The cost estimate I gave for the Northeast Corridor is $13 billion, the difference with $15 billion being rolling stock, which in that post I bundled into operating costs. With that estimate, the line profits $1.7 billion a year, a 13% financial return. This incentivizes building more lines to take advantage of network effects: New Haven-Springfield, Philadelphia-Pittsburgh, Washington-Virginia-North Carolina-Atlanta, New York-Upstate.
The problem: building extensions does require the infrastructure on the Northeast Corridor that I don’t think should be in the initial scope. Boston-Washington is good for around a 16-car train every 15 minutes all day, which is very intense by global standards but can still fit in the existing infrastructure where it is two-track. Even 10-minute service can sometimes fit on two tracks, for example having some high-speed trains stop at Trenton to cannibalize commuter rail traffic – but not always. Boston-Providence every 10 minutes requires extensive four-tracking, at least from Attleboro to beyond Sharon in addition to an overtake from Route 128 to Readville, the latter needed also for 15-minute service.
More fundamentally, once high-speed rail traffic grows beyond about 6 trains per hour, the value of a dedicated path through New York grows. This is not a cheap path – it means another Hudson tunnel, and a connection east to bypass the curves of the Hell Gate Bridge, which means 8 km of tunnel east and northeast of Penn Station and another 2 km above-ground around Randall’s Island, in addition to 5 km from Penn Station west across the river. The upshot is that this connection saves trains 3 minutes, and by freeing trains completely from regional rail traffic with four-tracking in the Bronx, it also permits using the lower 4% schedule pad, saving another 1 minute in the process.
If the United States is willing to spend close to $100 billion high-speed rail on the Northeast Corridor – it isn’t, but something like $40-50 billion may actually pass some congressional stimulus – then it should spend $15 billion and then use the other $85 billion for other stuff. This include high-speed tie-ins as detailed above, as well as low-speed regional lines in the Northeast: new Hudson tunnels for regional traffic, the North-South Rail Link, RegionalBahn-grade links around Providence and other secondary cities, completion of electrification everywhere a Northeastern passenger train runs
I hate the term “incremental” when it comes to infrastructure, not because it’s inherently bad, but because do-nothing politicians (e.g. just about every American elected official) use it as an excuse to implement quarter-measures, spending money without having to show anything for it.
So for the purpose of this post, “incremental” means “start with $15 billion to get Boston-Washington down to 3:20 and only later spend the rest.” It doesn’t mean “spend $2 billion on replacing a bridge that doesn’t really need replacement.”
With that in mind, the capacity increases required to get from bare Northeast Corridor high-speed rail to a more expansive system can all be done later. The overtakes on Baltimore-Washington would get filled in to form four continuous tracks all the way, the ones on Boston-Providence would be extended as outlined above, the bypasses on New York-New Haven would get linked to new tracks in the existing right-of-way where needed, the four-track narrows between Newark and Elizabeth would be expanded to six in an already existing right-of-way. Elizabeth Station has four tracks but the only building in the way of expanding it to six is a parking garage that needs to be removed anyway to ease the S-curve to the south of the platforms.
However, one capacity increase is difficult to retrofit: new tracks through New York. The most natural way to organize Penn Station is as a three-line system, with Line 1 carrying the existing Hudson tunnel and the southern East River tunnels, including high-speed traffic; Line 2 using new tunnels and a Grand Central link; and Line 3 using a realigned Empire Connection and the northern East River tunnels. The station is already centered on 32nd Street extending a block each way; existing tunnels going east go under 33rd and 32nd, and all plans for new tunnels continuing east to Grand Central or across the East River go under 31st.
But if it’s a 3-line system and high-speed trains need dedicated tracks, then regional trains don’t get to use the Hell Gate Line. (They don’t today, but the state is spending very large sums of money on changing this.) Given the expansion in regional service from the kind of spending that would justify so much extra intercity rail, a 4-line system may be needed. This is feasible, but not if Penn Station is remodeled for 3 lines; finding new space for a fourth tunnel is problematic to say the least.
The point of integrated timetable planning is to figure out what timetable one want to run in the future and then building the requisite infrastructure. Thus, in the 1990s Switzerland built the tunnels and extra tracks for the connections planned in Bahn 2000, and right now it’s doing the same for the next generation. This can work incrementally, but only if one knows all the phases in advance. If timetable plans radically change, for example because the politicians make big changes overruling the civil service to remind the public that they exist, then this system does not work.
If the United States remains uninterested in high-speed rail, then it’s fine to go ahead with a bare-bones $15 billion system. It’s good, it would generate good profits for Amtrak, it would also help somewhat with regional-intercity rail connectivity. Much of the rest of the system can be grafted on top without big changes.
But then it comes to Penn Station. It’s frustrating, because anything that brings it into focus attracts architects and architecture critics who think function should follow form. But it’s really important to make decisions soon, get to work demolishing the above-ground structures starting when the Madison Square Garden lease runs out, and move the tracks in the now-exposed stations as needed based on the design timetable.
As with everything else, it’s possible not to do it – to do one design and then change to another – but it costs extra, to the tune of multiple billions in unnecessary station reconstruction. If the point is to build high-speed rail cost-effectively, spending the same budget on more infrastructure instead of on a few gold-plated items, then this is not acceptable. Prior planning of how much service is intended is critical if costs are to stay down.
The MTA has weekly data on ridership by train station, which it divides into fare data, i.e. data by what kind of fare it is (single-use, monthly, etc.), and turnstile data, i.e. data by what bank of turnstiles was used to enter the station. MTA chief communications officer Abbey Collins talked to me briefly when I was writing this New York Daily News op-ed, and told me that the turnstile data is less accurate, so I am using the fare data.
Here is the table I’m using, comparing ridership in mid-January and the fourth week of March. It’s not fully sanitized, so some stations appear twice, which reflects multiple major entrances, e.g. the Times Square and the Port Authority sides of a single complex with in-system transfers. The relevant column is column E, labeled ratio. The highest-ratio station is Alabama Avenue on the J/Z, which has kept 53.5% of its January ridership; the next proper subway station, Bay Parkway on the F, is just at 38.6%, and it goes down from there. Overall, the ratio is 14.1%.
The general pattern is that the Manhattan CBD stations got pummeled. Grand Central has kept 7.5% of its pre-crisis ridership, and the Times Square side of the Times Square-Port Authority complex has kept 7.2%. A couple of Midtown and Lower Manhattan stations, like Rockefeller Center, are at the 5% mark. Practically no non-CBD station is this low, but one notable exception is Bedford Avenue on the L, in the center of Williamsburg. A few additional notable areas are in the 8-10% area, including more stations in Williamsburg, stations in Downtown Brooklyn and South Brooklyn, most stations on Central Park West, and Columbia. It’s notable that Columbia is low even though it has a major hospital, but it’s even more of a university.
Despite the stereotype, much of the Upper West and East Sides are not in the single digits. The key express stations, like 86th on the 4/5/6 and 72nd and 96th on the 1/2/3, are around 13-14%. Harlem is much higher, especially the busiest Harlem stations, 125th Street on the A/B/C/D and on the 4/5/6, both express stops, which have maintained 19.5% and 27.2% of ridership, respectively. 168th Street on the 1/A/C in Washington Heights is at 23.8%.
In general, working-class and lower middle-class stations seem to have maintained the most ridership. Jamaica Center, a key bus connection point to much of Eastern Queens, is by far the busiest among the >30% stations, at 35.3%. Utica Avenue on the 3/4 in Crown Heights is at 28.7%, and 149th Street on the 4/5/6 in the South Bronx is at 29.2%. Bedford-Stuyvesant is all over the map – Nostrand Avenue on the A/C is at 17.5%, Utica Avenue on the A/C is at 21.7%, the two Flushing Avenue stations are at about 27%, the Broadway stations on the J/Z past Flushing are in the teens.
I give those descriptive statistics because it relates to the question of subway ridership and the Covid-19 crisis. The crisis has hit outer neighborhoods harder than inner ones and working-class neighborhoods harder than middle-class ones, but beyond that pattern there is not much correlation at the level of detail. Bed-Stuy and Central Harlem have low infection rates and have maintained much more of their subway ridership than the city average.
The patterns probably concern essential workers. There are essential workers in all social classes, but more in the working class – cleaners, transit workers, sanitation workers, nursing assistants. The middle class supplies doctors and registered nurses, but there are fewer of these on the list of essential workers than lower-income, lower-education workers. Thus, middle-class neighborhoods, like the Upper East and West Sides, Astoria, Williamsburg, Sunnyside, Forest Hills, and Bay Ridge have below-average ratios, that is they’ve kept less of their ridership than the rest of the city.
One final pattern, or rather non-pattern, is that I can’t really see the hospitals on the table. The stations on the 2/5 closest to the Kings County Hospital, Winthrop Street and Church Avenue, are at 22.4% and 22.8% respectively, not too different from the rest of the Nostrand Avenue Line. The two Flushing Avenue stations have similar ratios, even though one is on top of Woodnull Medical Center and the other isn’t. 96th and 103rd Streets on the 6, the closest to Mount Sinai, have similar ratios to 110th and 116th farther up in East Harlem.
I refined my train performance calculator to automatically compute trip times from speed zones. Open it in Python 3 IDLE and play with the functions for speed zones – so far it can’t input stations, only speed zones on running track, with stations assumed at the beginning and end of the line.
I’ve applied this to a Northeast Corridor alignment between New York and Boston. The technical trip times based on the code and the alignment I drew are 0:36:21 New York-New Haven, 0:34:17 New Haven-Providence, 0:20:40 Providence-Boston; with 1-minute dwell times, this is 1:33 New York-Boston, rising to maybe 1:40 with schedule contingency. This is noticeably longer than I got in previous attempts to draw alignments, where I had around 1:28 without pad or 1:35 with; the difference is mainly in New York State, where I am less aggressive about rebuilding entire curves than I was before.
I’m not uploading this alignment yet because I want to fiddle with some 10 meter-scale questions. The most difficult part of this is between New Rochelle and New Haven. Demolitions of high-price residential properties are unavoidable, especially in Darien, where there is no alternative to carving a new right-of-way through Noroton Heights.
The importance of speeding up the slowest segments
The above trip times are computed based on the assumption that trains depart Penn Station at 60 km/h as they go through the interlocking, and then speed up to 160 km/h across the East River, using the aerodynamic noses designed for 360 km/h to achieve medium speed through tunnels with very little free air. This require redoing the switches at the interlocking; this is fine, switches in the United States are literally 19th-century technology, and upgrading them to Germany’s 1925 technology would create extra speed on the slowest segment.
Another important place to speed up is Shell Interlocking. The current version of the alignment shaves it completely, demolishing some low-rise commercial property in the process, to allow for 220 km/h speeds through the city. Grade separation is obligatory – the interlocking today is at-grade, which imposes unreasonable dependency between northbound and southbound schedules on a busy commuter railroad (about 20 Metro-North trains per hour in the peak direction).
In general, bypasses west of New Haven prioritize the slowest segments of the Northeast Corridor: the curves around the New York/Connecticut state line, Darien, Bridgeport. East of New Haven the entire line should be bypassed until Kingston, even the somewhat less curvy segment between East Haven and Old Saybrook, just because it’s a relatively easy segment where the railroad can mostly twin with I-95 and not have any complex viaducts.
The maximum speed is set at 360 km/h, but even though trains can cruise at such speed on two segments totaling 130 km, the difference in trip time with 300 km/h is only about 3 minutes. Similarly, in southwestern Connecticut, the maximum speed on parts of the line, mostly bypasses, is 250 km/h, and if trains could run at 280 km/h on those segments, which isn’t even always possible given curvature, it would save just 1 minute. The big savings come from turning a 10 miles per hour interlocking into a modern 60 km/h (or, ideally, 90+ km/h) one, eliminating the blanket 120 km/h speed limit between the NY/CT state line and New Haven, and speeding up throats around intermediate stations.
Bypasses are easier to draw than curve modifications. Curves on the Northeast Corridor don’t always have consistent radii – for example, the curves flanking Pawtucket look like they have radius 600 meters, but no, they have a few radii of which the tightest are about 400 meters, constraining speed further. Modifying such curves mostly within right-of-way should be a priority.
Going outside the right-of-way is also plausible, at a few locations. The area just west of Green’s Farms is a good candidate; so is Boston Switch, a tight curve somewhat northeast of Pawtucket whose inside is mostly water. A few more speculative places could get some noticeable trip time improvements, especially in the Bronx, but the benefit-cost ratio is unlikely to be good.
Bush consulting on takings
In some situations, there’s a choice of which route to take – for example, which side of I-95 to go on east of New Haven (my alignment mostly stays on the north side). Some right-of-way deviations from I-95 offer additional choice about what to demolish in the way.
In that case, it’s useful to look for less valuable commercial properties, and try to avoid extensive residential takings if it’s possible (and often it isn’t). This leads to some bush consulting estimates of how valuable a strip mall or hotel or bank branch is. It’s especially valuable when there are many options, because then it’s harder for one holdout to demand unreasonable compensation or make political threats – the railroad can go around them and pay slightly more for an easier takings process.
How fast should trains run?
Swiss planners run trains as fast as necessary, not as fast as possible. This plan does the opposite, first in order to establish a baseline for what can be done on a significant but not insane budget, and second because the expected frequency is high enough that hourly knots are not really feasible.
At most, some local high-speed trains could be designated as knot trains, reaching major stations on the hour or half-hour for regional train connections to inland cities. For example, such a local train could do New York-Boston in 2 hours rather than 1:40, with such additional stops as New Rochelle, Stamford, New London (at I-95, slightly north of the current stop), and Route 128 or Back Bay.
But for the most part, the regional rail connections are minor. New York and Boston are both huge cities, so a train that connects them in 1:40 is mostly an end-to-end train, beefed up by onward connections to Philadelphia, Baltimore, and Washington. Intermediate stops at New Haven and Providence supply some ridership too, much more so than any outlying regional connections like Danbury and Westerly, first because those outlying regional connections are much smaller towns and second much of the trip to those towns is at low speed so the trip time is not as convenient as on an all-high-speed route.
This does not mean Swiss planning maxims can be abandoned. Internal traffic in New England, or in Pennsylvania and South Jersey, or other such regions outside the immediate suburbs of big cities, must hew to these principles. Even big-city regional trains often have tails where half-hourly frequency is all that is justified. However, the high-speed line between Boston and New York (and Washington) specifically should run fast and rely on trips between the big cities to fill trains.
How much does it cost?
My estimate remains unchanged – maybe $7 billion in infrastructure costs, closer to $9-10 billion with rolling stock. Only one tunnel is included, under Bridgeport; everywhere else I’ve made an effort to use viaducts and commercial takings to avoid tunneling to limit costs. The 120 km of greenfield track between New Haven and Kingston include three major viaducts, crossing the Quinnipiac, Connecticut, and Thames; otherwise there are barely any environmentally or topographically sensitive areas and not many areas with delicate balance of eminent domain versus civil infrastructure.
I repeat, in case it is somehow unclear: for $7 billion in infrastructure investment, maybe $8 billion in year-of-expenditure dollars deflated to the early 2020s rather than early 2010s, trains could connect New York and Boston in 1:40. A similar project producing similar trip times between New York and Washington should cost less, my guess is around $3 billion, consisting mostly of resurrecting the old two-track B&P replacement in lieu of the current scope creep hell, building a few at-grade bypasses in Delaware and Maryland, and replacing the variable-tension catenary with constant-tension catenary.
None of this has to be expensive. Other parts of the world profitably build high-speed rail between cities of which the largest is about the size of Boston or Philadelphia rather than the smallest; Sweden is seriously thinking about high-speed trains between cities all of which combined still have fewer people than metropolitan Boston. Better things are possible, on a budget, and not just in theory – it’s demonstrated every few years when a new high-speed rail line opens in a medium-size European or Asian country.
New York is the capital of the coronavirus pandemic, with around 110,000 confirmed cases and 10,000 confirmed deaths citywide, and perhaps the same number across its suburbs. There must be many reasons why this is so; one possibility that people have raised is infection from crowded subways, so far without much evidence. Two days ago, MIT economist Jeffrey Harris wrote a paper claiming that the subways did in fact seed the Covid-19 epidemic in New York, but the paper cites no evidence. Sadly, some people have been citing the paper as a serious argument, which it isn’t; the purpose of this post is to explain what is wrong with the paper.
New York and other subways
In multiple other countries, one cannot see the transit cities in the virus infection rates. In Germany the rates in the largest cities are collectively the same as in the rest of the country. In South Korea, the infection is centered on Daegu; Seoul’s density and high transit usage are compatible with an infection rate of about 700 in a city of 9.5 million, about 1.5 orders of magnitude less per capita than in most Western countries and 2.5 orders of magnitude less than in New York. In Taipei, the MRT remains crowded, with weekday ridership in February and March down by 15-16%. In Italy, car usage is high outside a handful of very large cities like Milan, and Milan’s infection rate isn’t high by the standards of the rest of Lombardy.
However, rest-of-world evidence does not mean that the New York City Subway is safe. The Taipei MRT has mandatory mask usage and very frequent cleaning. German U- and S-Bahn networks are a lot dirtier than anything I’ve seen in Asia, but much cleaner than anything I’ve seen in New York, and also have much less peak crowding than New York. New York uniquely has turnstiles requiring pushing with one’s hands or bodies, and the only other city I know of with such fare barriers is Paris, whose infection rates are far below New York’s but still high by French standards.
So the question is not whether rapid transit systems are inherently unsafe for riders, which they are not. It’s whether New York, with all of its repeated failings killing tens of workers from exposure to the virus, has an unsafe rapid transit system. Nonetheless, the answer appears to be negative: no evidence exists that the subway is leading to higher infection rates, and the paper does not introduce any.
What’s in the paper?
A lot of rhetoric and a lot of lampshade hanging about the lack of natural experiments.
But when it comes to hard evidence, the paper makes two quantitative claims. The first is in figure 3: Manhattan had both the least increase in infections in the 3/13-4/7 period, equivalent to a doubling period of 20 days whereas the other boroughs ranged between 9.5 and 14, and also the largest decrease in subway entries in the 3/2-16 period, 65% whereas the other boroughs ranged between 33% and 56%.
The second is a series of maps showing per capita infection levels by zip code, similar to the one here. The paper also overlays a partial subway map and asserts that the map shows that there is correlation of infection rates along specific subway routes, for example the 7, as people spread the disease along the line.
I will address the second claim first, regarding line-level analysis, and then the first, regarding the borough-level difference-in-differences analysis; neither is even remotely correct.
Can you see the subway on an infection map?
Here is a static version of the infection map by zip code:
This is cases for 1,000 people – note that my post about Germany looks at rates per 10,000 people, so the range in New York is consistently about an order of magnitude worse than in Germany. The map shows high rates in Eastern Queens, the North Bronx, and Staten Island, hardly places with high public transportation ridership. The rates in Manhattan and the inner parts of Brooklyn are on the low side.
There are no ribbons of red matching any subway line – there are clumps and clusters, as in Southern Brooklyn in Orthodox Jewish neighborhoods, and in Central Queens around Corona and East Elmhurst. There is imperfect but noticeable correlation with income – working-class areas have higher infection rates, perhaps because they have higher rates at which people are required to still show up to work, where they can be infected. East Asian neighborhoods have lower rates, like Flushing and environs, or to some extent Sunset Park; Asians are infected at noticeably lower rates than others in New York and perhaps in the rest of the Western world, perhaps because they took news in China more seriously, began practicing social distancing earlier, and wear masks at higher rates. There are many correlates, none of which looks like it has anything to do with using the public transportation network.
What’s more, the paper is not making any quantitative argument why the graph shows correlation with subway usage. It shows the graph with some lines depicted, often misnamed, for example the Queens Boulevard Line is called Sixth Avenue Local, leading to a discussion about higher infection rates on local trains than on express trains where in fact the F runs express in Queens. But it does not engage in any analysis of rates of subway usage or changes therein, or in infection rates. The reader is supposed to eyeball the graph and immediately agree with the author’s conclusion, where there is no reason to do so.
The claim about Manhattan is the only real quantitative claim in the paper. Unlike the zip code analysis, the borough analysis does make some statistical argument: Manhattan had larger reduction in subway usage than the rest of the city and also a slower infection rate. However, this argument relies on an N of 2. Among the other boroughs, there is no such correlation. The argument is then purely about Manhattan vs. the rest of the city. This is incorrect for so many reasons:
- Manhattan is the highest-income borough, with many people who can work from home. If they’re not getting infected, it could be from not commuting as much, but just as well from not getting the virus at work as much.
- The Manhattan subway stops are often job centers, so the decline in ridership there reflects a citywide decline. A Manhattanite who stops taking the subway is seen as two fewer turnstile entries in Manhattan, whereas a New Yorker from the rest of the city who does the same is likely to be seen as one fewer Outer Borough entry and one fewer Manhattan entry.
- Many Manhattanites left the city to shelter elsewhere, as seen in trash collection data.
- Manhattan’s per capita subway usage is probably higher than that of the rest of the city counting discretionary trips, so 65% off the usual ridership in Manhattan may still be higher per capita than 56% off in Brooklyn or 47% in Queens. (But this is false on the level of commuting, where Manhattan, the Bronx, and Brooklyn all have 60% mode share.)
Does the paper have any value?
I have heard people on Twitter claim that correlation is not causation. This argument is too generous to the paper, which has not shown any correlation at all, since the only quantitative point it makes has an N of 2 and plenty of confounders.
For comparison, my analysis of metro construction costs has an effective N of about 40, since different subway projects in the same country tend to have similar costs with few exceptions (such as New York’s extreme-even-for-America costs), and I consider 40 to be low enough that Eric Goldwyn and I must use qualitative methods and delve deep into several case studies before we can confidently draw conclusions. The paper instead draws strong conclusions, even including detailed ones like the point the paper tries to make about local trains being more dangerous than express trains, from an N of 2; it’s irresponsible.
But what about the workers?
A large and growing number of New York City Transit workers have succumbed to the virus. The current count is close to the citywide death toll, but transportation workers are by definition all healthy enough to be working, whereas citywide (and worldwide) the dead are disproportionately old or have comorbidities like heart disease. Echoing the union’s demands for better protection, Andy Byford had unkind words to say about Governor Andrew Cuomo’s appointees in charge of the system, MTA chair Pat Foye and acting NYCT chair Sarah Feinberg.
However, this is not the same as infection among passengers. The dead include workers who are in close proximity to passengers on crowded vehicles, such as bus drivers, but also ones who are not, such as train operators, maintenance workers, and cleaners. Train cleaners have to remove contaminated trash from the platforms and vehicles without any protective equipment; NYCT not only didn’t supply workers with protective equipment, but also prohibited them from wearing masks on the job even if they’d procured them privately. Contamination at work is not the same as contamination during travel.
So, should people avoid public transportation in New York?
If the best attempt to provide evidence that riding the subway is a health hazard in a pandemic is this paper, then that by itself is evidence that there is no health hazard. This is true even given New York City Transit’s current level of dirt, though perhaps not given its pre-crisis peak crowding level. Social distancing is reducing overall travel and this is good, not necessarily because travel is hazardous, but mostly because the destination is often a crowded place with plenty of opportunity for person-to-person infection.
In preparation for going back to normal, the current level of cleanliness is not acceptable. The state should make sure people have access to masks, even if they’re ordinary ones rather than N95 ones, and mandate their usage in crowded places including the subway once they are available. It should invest far more in cleaning public spaces, including the subway, to the highest standards seen in the rich countries of Asia. It should certainly do much more to protect the workers, who face more serious hazards than the riders. But it should not discourage people who are traveling from doing so by train.
The US Census Bureau has just released 2019 population estimates by county. Metro New York, after slowly rising for decades more than making up the 1970s losses, went down by 60,000 people, or 0.3% of the population. The city is down 53,000 people.
The city chooses stagnation and ignorance. In the 1970s, the city was losing an average of 80,000 people per year, but the situation now is profoundly different. Incomes are up: the metro area’s per capita income as a proportion of the US average went from 126% in 1970 to 118% in 1980; but more recently it went from 135% in 2010-5 to 141% in 2018, the last year for which the BEA has data. Crime is down, the murder rate falling below the national average starting in 2013. Rent is up, sending a strong signal: more people want to live here.
But the entire political constellation of the city chooses not to grow. Housing growth is anemic, permits averaging around 21,000 per year in 2010-9, maybe 2.6 per 1,000 New York residents. It accelerated over the decade but not by much, reaching 26,500 in 2019, or 3.2/1,000. In the in-state suburbs, growth is even lower, less than 1 unit per 1,000 in each of Nassau, Suffolk, and Westchester Counties. New Jersey has somewhat higher growth rate, around 4/1,000, thanks to the Mount Laurel doctrine requiring high-cost municipalities to approve some affordable housing, which they typically do in the most out-of-the-way place they can find. The metro area overall approves about the same amount of housing as the city proper, around 2.5/1,000.
The most recent data I have for Korea is from the first half of 2019. In six months, Seoul, a shrinking city of 9.5 million, approved 38,000 dwellings, and the metro area writ large approved 129,000 on a population of about 26 million, an annualized rate of 10/1,000 (less in the city, more in the suburbs). This is a suburbanizing region, but suburbanization often means moving to a planned new town built on top of a subway or commuter rail line, like Ilsan, Bundang, and Anyang.
It’s not Tokyo that has high housing growth. It’s Tokyo, and Seoul, and to a lesser extent the metro area of Taipei (more suburbs than city proper), and Paris. In the presence of a strong economy and a state that doesn’t choose stagnation the way rich American regions choose with local empowerment, housing growth in a large city should be high, as more people want to move there to take advantage of its higher incomes and opportunities.
But New York chose differently. It chose stagnation and eventually decline. It chose to be expensive.
Why are they like this?
The US has an unusual system of governance, in which not only is there a separation of federal and state governments, as in Germany or Canada or Australia or Switzerland, but also the states delegate unusual powers to local governments. Education, policing, and housing are largely local responsibilities. Even when states do get involved, there is usually no partisan competition (most states are safe), leading to empowerment of local representatives on what are considered local issues, and even when there is people vote based on national issues.
But even that raises questions. For example, why do locals consider new development bad? Even YIMBY activists let NIMBYs whip them into thinking this way – they talk about sharing the burden, as if new buildings and new people are a burden that everyone must endure for some grand moral reason.
What if the reason people take it for granted that growth is bad is that the people who are most locally empowered are a specific anti-growth lobby? People who work for a living don’t have time to go to a citizen engagement meeting at 3 in the afternoon. They work and socialize with people from other neighborhoods, so they have little interest in neighborhood rags that report individual counts of parking spaces lost to a bus lane. They are far more interested in job growth than in hobby community gardens. A political system that requires very high levels of local social capital for one’s opinions to count will naturally undervalue their opinions and overvalue those of idle people and professional intermediaries.
The high levels of Covid-19 infection in New York are part of this system. The specific cause is not hyperlocalism, but rather the murky authority of the state. The city is plagued by the feud between Mayor de Blasio and Governor Cuomo. Both enjoy unlimited executive power, I think Cuomo more so than de Blasio. Both need it for their higher political aspirations. But neither can have it while the other exists as an independent political entity, nor is there a clear delineation of state and local authority. Thus, they are obligated to sabotage each other’s ideas, to the detriment of the city that has the misfortune to be governed by them. The entire West delayed its reaction to the virus, but New York especially so, as Cuomo and de Blasio tried denying each other credit.
I’ve been writing a lot about the role of incuriosity in high construction costs in the English-speaking world in general, and New York in particular – see for example this recent coronavirus-tainted piece, or this more random piece about Metro-North’s executives’ ignorance.
But this can apply more generally, as it did to the virus. Americans are quite provincial when it comes to the rest of the world, and New Yorkers especially so – go ahead, try telling a New Yorker that some other city does something better than New York. The out-of-town comparison, a powerful tool that places that view themselves as more peripheral (like Israel) use to correct errors, dos not work in a place like New York. New York literally made the collective decision to die and not to learn from the rest of the world. Mass death is not making New Yorkers demand the immediate removal of their mass manslaughterers who are their governor and mayor; why would a dip in population?
Part of it is related to local empowerment. Acquiring local social capital comes at the expense of worldliness; those years one spends learning foreign languages, living abroad, and socializing with foreigners are dead years for most political ambitions, including all ambitions that start locally.
But an even greater part of it is that New York self-perceives as the center of the world, which is not true elsewhere. Korea self-flagellates all the time: about its legal system (it adopted a limited jury system in 2009), about its engineering (see e.g. here), about its elevated air pollution levels (it’s adopting EU standards). The United States instead views all variations with the rest of the world as evidence of America’s unique greatness, and New York does the same both internationally and domestically. The city brims with immigrants, and yet it tells them, your home country is deficient and you must become a real New Yorker, that is someone whose world does not extend past city limits, to be a whole person. Until that changes, the government of New York will remain managed by dregs and incompetents and housing, transportation, and as we see health care will earn the mockery of other big first-world cities.
Entrenched hierarchies do not like outside criticism, especially when it’s right. They fight off knowledge that they don’t have or can’t control. In a business setting, the main way out is to found a competing company and drive the one that won’t change out of business. But when it’s not possible, the way out involves a massive crisis – something like a total war, in which people can rapidly rise through the ranks through demonstrating success in battle.
I bring this up because the coronavirus crisis in not such a total war. Branko Milanovic compares it with World War Two, contrasting economists who view it purely as an economic crisis akin to the 2008 crisis or the Depression. That comparison is apt when it comes to looking at non-economic aspects of it, namely the need to centrally plan a public health response. But the scale of the crisis is much smaller, it seems. The rich countries of Asia are emerging only somewhat battered, and even in the West some places seem to be over the hump judging by growth rates in the last few days, especially the Nordic countries but possibly also France. This isn’t the next Spanish Flu, a crisis so big that it would force Westerners to reckon with the fact that the West needs to learn from other places. Even in the United States, where things look worse, the solipsistic population looks for internal comparisons (e.g. between blue and red states) more than international ones, let alone international ones with Asia.
A small crisis is not going to nudge the hierarchy in a more open direction. I see this often in public transportation – institutions that feel embattled respond by entrenching and refusing any reform. The standard excuse is “we’re too busy fighting fires,” often by people that fires seem to erupt around regularly. The virus seems to have the same effect so far – less openness, less sanity checking proposals by looking at what works elsewhere, more digging in around traditional social hierarchies.
American nationalists are saber-rattling with the Chinese government, as in the “Chinese virus” dysphemism and Tom Cotton’s blaming the entire death toll on the PRC. But they still do this on the usual American terms, that is without any assurance that Taiwan is a success story to learn from, or even South Korea and Japan, two American allies that unlike Taiwan the US formally recognizes. If a virus that demonstrates to starkly that Taiwan governs itself better than the PRC won’t get American nationalists to start speaking favorably of Taiwan, what will? To people like Cotton, a crisis is a perfect time to proclaim American superiority, no matter what reality is.
Domestically, too, the American response seems to be to repeat old wives’ tales – for example, traditional American hostility to big cities. Governor Andrew Cuomo went as far as saying that New York is too dense; Seoul, a bigger and denser city, has 700 infections as of 2020-3-22 out of a metro population of 26 million, maybe a factor of 20 better than New York. But he’s the governor and he keeps giving speeches and appearing on television, and a few hundred and even a few thousand dead New Yorkers is not enough to make people ask questions about his and Mayor Bill de Blasio’s squabbling. After all, when nearly 3,000 New Yorkers died on 9/11, few asked why Mayor Rudy Giuliani had put the city’s anti-terrorism response center at World Trade Center against the advice of security experts who pointed out the Twin Towers were a likely target; 9/11’s effect on Giuliani’s popularity was an unmixed blessing.
In an environment in which more national pundits say Cuomo is looking presidential than say he should resign in disgrace, it’s unlikely the crisis will lead Americans in a more open direction. The magnitude of the crisis isn’t enough to create a new crop of leaders. It’s a good thing in the sense that the death toll will not be apocalyptic, but it just underscores what I mean when I say this isn’t World War Two.
Budget-cutting administrations, demanding reform before revenue, have not produced any reform. American state building stalled in the middle of the 20th century when various white middle-class interests realized localism could protect them from too much racial and economic equality. Then around the 1980s and 90s it went into reverse, with a continued assault on state capacity through public-private partnerships, outsourcing planning to consultants, and impositions of managers whose experience was in the private sector in unrelated industries. American construction costs were already high beforehand, but in Canada and Singapore, both of which seem to have had the same trend, costs exploded in the 2000s and 2010s.
The question remains: how come the reform-before-revenue mentality never produced any reform?
I bring this up because I believe the answer is the same as what we are seeing right now with the response to the coronavirus crisis. Budget-cutting or timid politicians are not an existential crisis to the civil service. They can scare off ambitious people the way Cuomo ran Andy Byford out of New York City Transit leadership; they can create a hostile work environment; they can force managers to contend with scarcity; they can force the unions to agree to wage reductions for entering workers. But they do not have the power to close entire departments, to stop running schools or public transportation or firefighting entirely, and the managers and workers both know this.
Just as the Covid-19 crisis is not World War Two, all attempts at privatizing the state in the Anglosphere have amounted to much less than a total war of extermination. It’s a cold war. Like the original Cold War, it has the same stupefying effect as a hot war – hierarchs are all too happy to be unaccountable to the broad public and to pretend their cloak-and-dagger politics achieve any results. Unlike a hot war, it is too low-intensity for people who disagree with the hierarchy but are right to demonstrate competence – nor is the other side going to be destroyed at the end.
The construction cost crisis in the United States, particularly New York, might actually be a big enough crisis to have the same effect on the established order as a total war. It’s unclear, but before the virus came to the United States, there was a lot of genuine interest in making things better, though not in every city.
I suspect the mechanism for costs is that they are so high that there must be a significant enough reduction to make a career without screwing some politically necessary constituency. I don’t know; I don’t yet know the drivers of high New York costs in sufficient detail. But the magnitude and breadth of the problem point to many different explanations each increasing costs by a significant but not apocalyptic amount. Moreover, the fact that there must be many causes seems to be accepted in the local political ecosystem. Thus, people can afford to make reforms, perhaps focusing on the politically low-hanging fruits.
This is less cynical than it may sound. A small success story, such as if Ned Lamont had figured out a way to build 30-30-30 or if the MTA manages to noticeably reduce the cost of some project, creates a visible trail of success, creating more pressure to keep the reforms. Nothing succeeds like success.
A New York that can build subways even at $300 million per kilometer, let alone $100 million per kilometer, and builds housing at a pace befitting a rich global city with considerable immigration, is a completely different place from the failed city that it is today. That New York is a dynamic, rapidly growing city in which there is far more kvetching about how it’s sucking in jobs and people from more static places than kvetching about how it’s exporting jobs and people to cheaper places. I’m using analogy here because low costs by themselves do not protect a city from disease (Italy and Switzerland both have low costs and high coronavirus infection levels), but the same kind of public-sector resurgence can presumably be done for public health, ensuring New York will respond to the next pandemic like Seoul or Tokyo or Taipei.
If Swiss planners were hired to design an intercity rail network for New York State, they might propose something that looks like this:
The trip times depicted on the map are a few minutes longer than intended, especially next to a terminus station like Niagara Falls, Watertown, and Ithaca. The depicted times are inclusive of turnaround time: the 45-minute Buffalo-Niagara Falls line is intended to take around 35 minutes in actual service, with 10-minute turnarounds.
Swiss planning is based on hourly and half-hourly timetables repeating all day on a clockface pattern: if a train leaves your station at 8:24 am, a train will leave your station at xx:24 all day, and if the line runs every half hour then also at xx:54. Moreover, at major nodes, trains are timetabled to arrive a few minutes before the hour and depart a few minutes after, letting passengers connect between different trains with minimal wait. To minimize transfer time and turn time, trains run as fast as necessary – that is, the state invests in higher-speed lines to ensure connections between major cities take a few minutes less than an hour. The Bahn 2000 program set up connections between Zurich, Basel, and Bern taking just less than an hour, with a few further connections elsewhere taking just less than an integer number of half-hours; the Bahn 2030 program aims to do the same with more cities all over the country.
The above map is an adaptation of the concept to New York State. I hope the explanation of how to adapt Switzerland to New York will be of interest to rail advocates elsewhere – the differences between the two geographies matter elsewhere, for example in Germany, France, or Sweden, or for that matter in California or New England.
There is no high-speed rail in Switzerland, unless one counts the mixed passenger and freight rail tunnels through the Alps, which allow 250 km/h passenger trains. The Bahn 2030 planning calls for a 2-hour trip time between Zurich and Lugano, a distance of about 170 km, even with heavy tunneling under all significant mountains; with so much tunneling, 1.5-hour trips are easy and even 1-hour trips are feasible with a bypass around Zug. Clearly, even when higher speeds are allowed, Swiss planning sticks to low- and medium-speed rail, targeting an average speed of about 120 km/h.
This works for Switzerland, a small country in which even Geneva is only 2:45 from Zurich. In New York, it does not. At the speed of upgraded legacy rail, comparable to the Northeast Corridor, the links on the above map along the high-speed spine would take 2 hours each rather than an hour. New York-Buffalo trains would take 6 hours, too long for most travelers, and New York-Rochester would take 5 hours, which is marginal at best. Trains doing New York-Albany in 2 hours could get fairly popular, but even that is long enough that cutting it to just less than an hour is feasible.
Trains are to run every half hour, with the exception of urban lines, namely Buffalo-Niagara Falls, Albany-Troy-Mechanicsville, and Utica-Rome, which run every 15 minutes. The reason for the half-hourly frequency is that all lines need it for either capacity or ridership. The lines either run to New York, which is so big it can easily fill a train every half hour and perhaps even every 15 minutes, or are quite short, so that running only every hour reduces ridership and it’s better to run shorter trains every 30 minutes.
With half-hourly timetables, a stub-end line can take an integer number of quarter-hours and not just half-hours. For example, Syracuse and Albany should have a pulse at :00 and :30 every hour. This in turn means that trains from Albany to Glens Falls can take 1:15, departing Albany just after :00 and :30, arriving at Glens Falls just before :15 and :45, turning back toward Albany just after :15 and :45, and then returning to Albany just before :00 and :30.
The only worry with quarter-hour trip times is that every cycle must sum up to an integer number of half-hours, not quarter-hours. Otherwise, some connections are broken, offset by 15 minutes. Thankfully, the only cycle on this map is New York-Albany-Syracuse-Binghamton-New York, which takes 7 hours.
Syracuse regional rail
Syracuse is depicted as having the most expansive regional rail network in the state, despite being the smallest of Upstate New York’s four major metropolitan areas. The reason is that the goal of the planned network is to provide intercity rather than local service. Rochester has some useful urban lines, for example to Freeport or northwest to the lakefront, but they are so short that they should run every 10 or 15 minutes and not every half hour. However, Rochester has no significant independent towns within an hour or so by rail, and thus there are no timed connections there. In contrast, Syracuse is located right between Watertown, Oswego, Auburn, and Cortland with its connection onward to Ithaca.
The Syracuse system is intended to be fully on the RegionalBahn side of the S-Bahn vs. RegionalBahn divide. The shared segment between Syracuse and the split between the lines to Oswego and Watertown is not meant to overlay to run frequent urban service. Instead, trains should tailgate, followed by a gap of nearly half an hour. Syracuse-bound trains may well call at Liverpool at :20 and :22, arriving at Syracuse at :25 and :27 to exchange passengers with other trains and then continue south, one of Oswego and Watertown paired with Cortland and Binghamton and the other terminating. If north-south S-Bahn service is desired, trains should be slotted in between the intercity trains.
The map depicts greenfield alignments for the high-speed line except on the approaches to New York and Toronto, and legacy alignments for the low-speed lines.
As in Switzerland, the low-speed lines do not necessarily slavishly adhere to legacy alignments. However, the deviations are not the same. Switzerland uses bypasses and tunnels to speed lines up. In New York, the main mechanisms to speed up lines are electrification, track renewal, and higher superelevation. Tunnels are too expensive for the population density of Upstate New York. I can see some bypasses, potentially getting Syracuse-Cortland and Cortland-Binghamton down to 30 minutes each, but none of the Upstate cities off the high-speed line is big enough to justify major civil works.
The one depicted bypass on a blue-colored line is the use of the Boonton Branch in New Jersey to offer an express bypass around the Morristown Line with its dense station spacing. This requires some additional tracks on busy urban regional lines as well as a short tunnel in Paterson, but New York is big enough that investing in faster service to Dover, Delaware Water Gap, and Scranton is worth it.
Upstate, the important deviations involve restoring old tracks, including between Cortland and Ithaca and within some town centers. Corning and Glens Falls both have disused rail alignments serving their centers better than the existing freight lines. But most importantly, Syracuse has an underused freeway running east-west through its center, which I am assuming replaced with a rail line. This is not a new idea – Syracuse is already removing a branch of the freeway, which should be used for a rail connection toward Binghamton, and even the mainline is a vestige of when midcentury planners thought Upstate cities would keep growing. The current Syracuse station is at an inconvenient location, making rail realignment a good use of the right-of-way.
New York State is much more integrated with its neighbors than Switzerland – it’s all the same country. There is extensive interstate travel, and rail planning must accommodate this. Forget the Deutschlandtakt – an Americatakt would be the most complex rail plan in a developed country out of sheer size. Thankfully, the connections depicted on the New York State plan accommodate interstate travel fairly well.
Going east, there are connections to Vermont, Massachusetts, and Connecticut. Albany-Boston can be done in around an hour, which makes for a half-hour takt connection between Albany and Springfield and 45 minutes minus turnaround between Springfield and Boston. Springfield-New Haven is 30 minutes by high-speed rail or 45 minutes by fast legacy rail, both with a stop at Hartford and few to no others; Springfield can then get its own small regional rail line toward Northampton (with some urban overlays for an S-Bahn) and Greenfield. Vermont can get a slow line to Rutland, and/or a fast line to Burlington continuing to Montreal; thence New York-Montreal and Boston-Toronto trains can be timed to connect at Albany, with New York-Toronto trains slotted in between, timed to connect only to the more frequent urban lines like Buffalo-Niagara Falls.
Going south, New York is separated from Pennsylvania by the northern reach of the Appalachians, called the Southern Tier in New York and the Northern Tier in Pennsylvania. This area had many coal mines in the 19th century and as a result has many legacy rail lines, but they are curvy and connect villages. But Scranton is a significant city on a nice line with Allentown and Philadelphia; unfortunately, the Philadelphia-Allentown line stretches via Reading and the Allentown-Scranton line is hilly and curvy, justifying some greenfield construction with some tunneling near the northern end.
Finally, going west, the I-90 route serves Erie and the Midwest. But this is a plausible high-speed rail connection toward Chicago, and so no low-speed interface is needed within the state. Erie could get a line to Youngstown and Pittsburgh, but it would be slower than connecting between high-speed trains in Cleveland; the largest city between Erie and Youngstown is Meadsville, population 13,000.
The cost of the high-speed spine is considerable, but if New York can keep it to the level of France (around $25 million/km), or even Germany (around $35 million/km), the benefits should exceed the costs. New York is huge, and even though nothing in Upstate New York is, the combined populations of Syracuse, Rochester, and Buffalo would add up to a big French or German city. And then there is Toronto at the other end, anchoring everything.
The low-speed lines should be quite cheap. Track renewal in Germany is around $1 million per single-track kilometer; at the frequency envisioned, all the low-speed lines can stay single-track with passing segments. Electrification is maybe $1.5 million per kilometer in Israel, despite a lawsuit that delayed the project by three years.
Is this feasible?
Technically, all of this is feasible. Good transit advocates in the Northeastern United States should push elected officials at the federal and state levels to quickly plan such a system and aim to begin construction early this decade. Bahn 2000 was supposed to take the 1990s to be built, but was delayed to 2004; this is a bigger program but can still happen by 2030 or so.
The trip times, frequencies, and coverage chosen for the map are deliberately conservative. It’s possible to squeeze higher speed at places, and add more branches to smaller towns, like Rochester-Niagara Falls or Buffalo-Jamestown. Bahn 2000 is followed up with Bahn 2030 or Bahn 2035, and likewise rail improvements can accrete in the United States. But as a starter system, this is a solid network connecting all large and nearly all small cities in New York State to one another with maximum convenience and minimum hassle. I hope state planners take heed and plan to invest soon.
Imagine yourself taking a train somewhere, and imagine the train is big and infrequent. Let’s say it’s the commuter train from New York down the Northeast Corridor to Newark Airport, or perhaps a low-cost OuiGo TGV from Lyon to Paris. Now imagine that you change trains to a small, frequent train, like the AirTrain to Newark Airport, or the RER from the OuiGo stop in the suburbs to Paris itself. What do you think happens?
If your guess is “the train I’m connecting to will be overcrowded,” you are correct. Only a minority of a 200 meter long New Jersey Transit train’s ridership unloads at the Newark Airport station, but this minority is substantial enough to overwhelm the connection to the short AirTrain to the terminals. Normally, the AirTrain operates well below capacity. It uses driverless technology to run small vehicles every 3 minutes, which is more than enough for how many people connect between terminals or go to New York by train. But when a big train that runs every 20-30 minutes arrives, a quantity of passengers who would be easily accommodated if they arrived over 20 minutes all make their way to the monorail at once.
In Paris, the situation is similar, but the details differ. Until recently, OuiGo did not serve Paris at the usual terminal of Gare de Lyon but rather at an outlying station near Eurodisney, Marne-la-Vallée-Chessy, ostensibly to save money by avoiding the Gare de Lyon throat, in reality to immiserate passengers who don’t pay full TGV fare. There, passengers would connect from a 400-meter bilevel TGV on which the entire train ridership would get off to a 220-meter bilevel RER train running every 10 minutes. The worst congestion wasn’t even on the RER itself, but at the ticket machines: enough of the thousand passengers did not have Navigo monthly cards for the RER that long lines formed at the ticket machines, adding 20 minutes to the trip. With the RER connection and the line, the trips would be nearly 3.5 hours, 2 spent on the high-speed train and 1.5 at the Paris end.
I even saw something similar in Shanghai in 2009. I visited Jiaxing, an hour away at the time by train, and when I came back, a mass of people without the Shanghai Public Transportation Card overwhelmed the one working Shanghai Metro ticketing machine. There were three machines at the entrance, but two were out of service. With the 20 minutes of standing in line, I would have gotten back to my hotel faster if I’d walked.
This is a serious problem – the ticketing machine lines alone can add 20 minutes to an otherwise 2.5-hour door-to-door trip. To avoid this problem, railroads and transit agencies need a kit with a number of distinct tools, appropriate for different circumstances.
Run trains more frequently
Commuter trains have to run frequently enough to be useful for short-distance trips. If the RER A consistently fills a train every 10 minutes off-peak between Paris and Marne-la-Vallée, New Jersey Transit can consistently fill a local train every 10 minutes off-peak between Manhattan and New Brunswick. Extra frequency induces extra ridership, but fewer people are going to get off at the Newark Airport stop per train if trains run more often. There are some places where adding frequency induces extra ridership proportionately to the extra service, or even more, but they tend to be shorter-range traffic, for example between Newark and Elizabeth or between Newark and New York.
This tool is useful for urban, suburban, and regional service. A train over a 20 kilometer distance can run frequently enough that transfers to more frequent shuttles are not a problem. Even today, this is mostly a problem with airport connectors, because it’s otherwise uncommon for outlying services to run very frequently. The one non-airport example I am familiar with is in Boston on the Mattapan High-Speed Line, a light rail line that runs every 5 minutes, connecting Mattapan with Ashmont, the terminus of the Red Line subway, on a branch that runs every 8-9 minutes at rush hour and every 12-15 off-peak.
In contrast, this tool is less useful for intercity trains. France should be running TGVs more frequently off-peak, but this means every half hour, not every 10 minutes. The only long-distance European corridors that have any business running an intercity train every 10 minutes are Berlin-Hanover(-Dortmund) and Frankfurt-Cologne, and in both cases it comes from interlining many different branches connecting huge metropolitan areas onto a single trunk.
Eliminate unnecessary transfers
The problem only occurs if there is a transfer to begin with. In some cases, it is feasible to eliminate the transfer and offer a direct trip. SNCF has gradually shifted OuiGo traffic from suburban stations like Marne-la-Vallée and Massy to the regular urban terminals; nowadays, five daily OuiGo trains go from Lyon to Gare de Lyon and only two go to Marne-la-Vallée.
Gare de Lyon is few people’s final destination, but at a major urban station with multiple Métro and RER connections, the infrastructure can handle large crowds better. In that case, the transfer isn’t really from an infrequent vehicle, because a TGV, TER, or Transilien train unloads at Gare de Lyon every few minutes at rush hour. The Métro is still more frequent, but at the resolution of a mainline train every 5 minutes versus a Métro Line 1 or 14 train every 1.5 minutes, this is a non-issue: for one, passengers can easily take 5 minutes just to walk from the far end of the train to the concourse, so effectively they arrive at the Métro at a uniform rate rather than in a short burst.
Of note, Shanghai did this before the high-speed trains opened: the trains served Shanghai Railway Station. The capacity problems occurred mostly because two out of three ticketing machines were broken, a problem that plagued the Shanghai Metro in 2009. Perhaps things are better now, a decade of fast economic growth later; they certainly are better in all first-world cities I’ve taken trains in.
Eliminating unnecessary transfers is also relevant to two urban cases mentioned above: airport people movers, and the Mattapan High-Speed Line. Airport connectors are better when people do not need to take a landside people mover but rather can walk directly from the train station to the terminal. Direct service is more convenient in general, but this is especially true of airport connectors. Tourists are less familiar with the city and may be less willing to transfer; all passengers, tourists and locals, are likely to be traveling with luggage. The upshot is that if an airport connector can be done as an extension of a subway, light rail, or regional rail line, it should; positive examples include the Piccadilly line and soon to be Crossrail in London, the RER B in Paris, and the S-Bahn in Zurich.
The Mattapan High-Speed Line’s peculiar situation as an isolated tramway has likewise led to calls for eliminating the forced transfer. Forces at the MBTA that don’t like providing train service have proposed downgrading it to a bus; forces within the region that do have instead proposed making the necessary investments to turn it into an extension of the Red Line.
Simplify transfer interfaces
The capacity problem at the transfer from an infrequent service to a frequent one is not just inside the frequent but small vehicle, but also at the transfer interface. Permitting a gentler interface can go a long way toward solving the problem.
First, tear down the faregates. There should not be fare barriers between different public transport services, especially not ones where congestion at the transfer point can be expected. Even when everything else is done right, people can overwhelm the gates, as at the Newark Airport train station. The lines aren’t long, but they are stressful. Every mistake (say, if my ticket is invalid, or if someone else tries to ask the stressed station agent a question) slows down a large crowd of people.
And second, sell combined tickets. Intercity train tickets in Germany offer the option of bundling a single-ride city ticket at the destination for the usual price; for the benefit of visitors, this should be expanded to include a bundled multi-ride ticket or short-term pass. New Jersey Transit sells through-tickets to the airport that include the AirTrain transfer, and so there is no congestion at the ticketing machines, only at the faregates and on the train itself.
Both of these options require better integration between different service providers. That said, such integration is clearly possible – New Jersey Transit and Port Authority manage it despite having poor fare and schedule integration elsewhere. In France in particular, there exist sociétés de transport functioning like German Verkehrsverbünde in coordinating regional fares; SNCF and RATP have a long history of managing somehow to work together in and around Paris, so combined TGV + RER tickets, ideally with some kind of mechanism to avoid forcing visitors to deal with the cumbersome process of getting a Navigo pass, should not be a problem.
I wrote a post about American moral panics about fare evasion two months ago, which was mirrored on Streetsblog. I made a mistake in that post that I’d like to correct – and yet the correction itself showcases something interesting about why there are armed police on trains. In talking about BART’s unique belts-and-suspenders system combining faregates with proof-of-payment fare inspections, I complained that BART uses armed police to conduct inspections, where the German-speaking world happily uses unarmed civilians. BART wrote me back to correct me – the inspections are done by unarmed civilians, called ambassadors. The armed cops on the trains are unrelated.
I’d have talked about my error earlier, but I got the correction at the end of November. The American Christmas season begins around Thanksgiving and ends after Sylvester, and in this period both labor productivity and news readership plummet; leave it to Americans to have five weeks a year of low productivity without giving workers those five weeks in vacation time. With that error out of the way – again, BART conducts inspections with unarmed ambassadors, not armed cops – it’s worth talking about why, then, there are armed cops on trains at all, and what it means for fare enforcement.
The answer to the “why armed cops on the train?” question is that among the broad American public, the police is popular. There are hefty differences by party identification, and in the Bay Area, the opinions of Republicans are mostly irrelevant, but even among Democrats; there are also hefty differences by race, but blacks are at their most anti-police divided on the issue. A Pew poll about trust in institutions asks a variety of questions about the police, none of which is “would you like to see more cops patrol the subway?”, but the crosstabs really don’t scream “no.” Vox cites a poll by Civis Analytics that directly asks about hiring more police officers, and even among black people the results are 60-18 in favor. In New York, NYPD Commissioner James O’Neill had positive net approval among all racial groups shortly before leaving office, the lowest rate being 43-28 among Hispanics.
The crosstabs only go so far, and it’s likely that among certain subgroups the police is much less popular, for example black millennials. It’s normal for a popular institution to still generate intense opposition from specific demographic, class-based, or ideological groups, and it’s even normal for a popular institution to be bad; I should know, Massachusetts’ Charlie Baker is one of America’s most popular governors and yet his do-nothing approach to infrastructure planning makes him unpopular at TransitMatters. But this doesn’t change the fact that, as a positive rather than normative statement, the police enjoys consensus support from the urban American public.
What this means is that there are cops on the subway in New York and on BART not because of an inherent necessity of the fare collection system, but because in the eyes of the people who run these systems, crime is a serious concern and having more cops around is the solution. Evidently, BART layers cops on top of two distinct fare enforcement mechanisms – fare barriers and the ambassadors. In New York, too, NYPD’s justification for arresting people for jumping the turnstiles is that a significant fraction of them have outstanding warrants (many of which are about low-level offenses like being behind on court payments).
I bring this up because there’s a growing argument on the American left that public transportation should be free because that way people won’t be arrested for fare-dodging. This argument slides in an assumption, all too common to socialists who are to the left of the mainline liberal or social democratic party, that there is a leftist majority among the public that is just waiting to be activated by a charismatic leader rejecting neoliberal or otherwise moderate political assumptions.
But in the real world, there is no such leftist majority. The median voter even in a very left-wing area like New York or San Francisco may not support the more violent aspects of tough-on-crime politics, but is mostly okay with more police presence. The average self-identified leftist may be more worried that having police patrols will lead to more brutality than that not having them will lead to more crime, but the average self-identified leftist is not the average voter even in the Bay Area.
In this reality, there are cops on the subway because a lot of people worry about crime on the subway and want to see more police presence. The cops themselves, who are well to the right of the average voter pretty much anywhere, may justify this in terms of fare beating, but what matters is what voters near the median think, and they worry about ordinary property and violent crime. Those worries may well be unfounded – for one, New York is very safe nowadays and has been getting steadily safer, so the recent binge of hiring more cops to patrol the subway is a waste of money – but so long as voters have them, there will be police patrols.
The upshot is twofold. First, fare enforcement and the politics of criminal justice have very little to do with each other. Cops patrol crowded public spaces that require payment to enter, like the subway, as they do crowded public spaces that do not, like city squares. If public transportation fares are abolished, cops will likely keep patrolling subway stations, just as they patrol pieces of transportation infrastructure that are fare-free, like the concourses of major train stations.
If the left succeeds in persuading more people that the police is hostile to their interests and the city is better off with less public police presence, then cops will not patrol either the subway or most city squares. In the future, this is not outside the realm of possibility – in fifteen years the popularity of same-sex marriage in the US went from about 2-to-1 against to 2-to-1 in favor, and the trend in other democracies is broadly similar. But in New York and San Francisco in 2020, this is not the situation.
And second, fare enforcement can be conducted with unarmed inspectors regardless of the political environment. Multiple Americans who express fear of crime have told me that inspections have to be done with armed police, because fare beaters are so dangerous they would never submit to an unarmed inspector. And yet, even in San Francisco, where a large fraction of the middle class is worried about being robbed, inspections are done without weapons.
I’ve recurrently told American cities to tear down the faregates. BART’s belts-and-suspenders fare enforcement is unnecessary, borne of a panic rather than of any calculation of costs and benefits to the system. But what BART should get rid of is not the ambassadors, but the faregates. The most successful transit city the rough size of San Francisco – Berlin – has no faregates and leaves most stations unstaffed to reduce costs. Berlin encourages compliance by making it easier to follow the law, for example by offering cheap monthly passes, rather than by hitting passengers in the face with head-level fare barriers.
If cops patrol the subway because most voters and most riders would prefer it this way, then there is no need to connect the politics of policing with the technical question of what the most efficient way to collect fares is. There is a clear best practice for the latter, and it does not involve faregates in a rapid transit system with fewer than multiple billions of annual riders. What the police does is a separate question, one that there is no reason to connect with how to raise money for good public transportation.
